Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability synthora-openfda-medical-device-adverse-events-maude-a5989953 -d '<json body>'
```

Example prompt: Search the FDA MAUDE database for adverse event reports on insulin pumps — show me the top 20 results including device name, manufacturer, and whether events were malfunctions, injuries, or deaths.

## When to prefer this

Choose this endpoint when you need structured, queryable access to FDA MAUDE adverse-event data without building your own openFDA integration — especially in automated medtech safety-surveillance pipelines, device procurement risk scoring, or agent-to-agent workflows that rank devices by malfunction and injury frequency. Prefer it over direct openFDA calls when cost-per-query pricing and x402 micropayment compatibility are needed for autonomous agent workflows.

## Known failure modes

- Invalid search syntax causes openFDA API to return an error or empty result set
- Requesting a limit beyond openFDA's maximum returns a partial or error response
- Device name with no MAUDE records returns an empty result set
- Downstream openFDA API unavailability causes service failure
- Overly broad search terms may return irrelevant or overwhelming results

## How this service works

Returns FDA MAUDE medical-device adverse-event reports from openFDA api.fda.gov/device/event: device generic and brand name, manufacturer, event_type (malfunction/injury/death), patient outcomes and problem codes. Autonomous agents and agent-to-agent (A2A) medtech safety-surveillance and procurement-risk systems consume it to rank device reliability. Ranking surface: device name to malfunction/injury counts.

## Output

Returns a JSON object with a success flag and a result payload containing FDA MAUDE adverse-event records — including device generic and brand names, manufacturer, event_type (malfunction, injury, or death), patient outcome codes, and device problem codes — matching the search query and limited to the specified number of records.
